I pulled my CW9 for the first time yesterday (while hiking) but it was for 2 off-leash Rhodesian Ridgebacks (aka African Lion Dogs) that ran about 100 yards to get to me and my German Sheperd. Long story short, they didn't attack but many non-dog people would possibly have shot them. I say this because there were some small clues that they might not attack. It was a close call and if I had seen one tooth touch my dog I was prepared to shoot (the gun was pointed at them for about 3 seconds) ... my finger never touched the trigger. The 31 year old man I was hiking with didn't respond to my commands (I told him to take my dog's leash) ... he later admitted that he had an adrenaline rush and that his heart rate was very high.
Bottom line - turned out well, finger was never on the trigger and I am going to Sportsman's Warehouse today to pick up some bear spray for situations like this. I'd rather have some bear spray be my first line of defense, IF POSSIBLE.
